Speeication of Letters Patent.

Patented July 9, 1907.

Application filed September 21,1906. Serial No. 335,589.

To all whom it may concern:

Be it known that we, FREDERICK OBERBECK, a resident of New Athens, inthe county of St. Clair and State of Illinois, and CARL TRUE TAYLOR, aresident of Mount Sterling, in the county of Brown and State ofIllinois, and both citizens of the United States, have invented a newand Improved Cooking-Stove, of which the following is a full, clear, andexact description.

This invention relates to a new and improved cooking stove, and has forits object to provide a much simpler and more economically operatingstove than any heretofore used.

In our improved cooking stove, as hereinafter de scribed, fresh heatedair is admitted to the oven, causing the evaporation to take placefaster and thereby removing the moisture from the material being cookedand causing such material, particularly bread, to bake much quicker. Thefresh outside air is admitted to a special heating chamber, wherein itis heated to a very high temperature and then delivered to the oven andcaused to circulate therethrough to take up the moisture and heat thefood, the moisture-laden air carrying the odors being caused to escapeup the chimney rather than into the room. The 'fire passes over theentire heating chamber and comes in contact with a very large heatingsurface, so that the air is very quickly heated and a rapid circulationthereof is effected. The oven is also heated by the Contact of the hotflames with certain of the walls, so that baking can be effected eventhough the air circulation is entirely shut off. The oven being locatedat the rear end of the stove, the front portion thereof may be used forordinary cooking purposes without being interfered with or interferingin any way with the operation of the oven.

A further object of our invention is to reduce the number of flues anddampers existing in the common form of cooking stoves, so that there areno recesses or passages to become clogged up with soot and ashes andinterfere with the draft, The small number of dampers employed rendersthe stove very simple, and the improved means for providing aircirculation through the oven results in more thoroughly, evenly, quicklyand healthfully cooking the food.

Reference is to be had to the accompanying drawings forming Aa part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, in which Figure l is a sideelevation of our improved cooking stovie, Fig. 2 is a plan view thereof;Fig. 3 is a vertical p section on the line 3-3 of Fig. 2; and Fig. 4 isa vertical section on the line 4-4 of Fig. 3.

Our improved cooking stove comprises a rectangular body portion l,having oven 2 located thereon adjacent the rear end, and having the mainbody portion of the stove sub-divided by a plurality of partitions toform the various compartments. A vertical partition 3 extends from thelower portion of the stove to a point adjacent the/top thereof, andserves to separate the fire-box from a hot water reservoir 4. Thefire-box is provided with the usual lining 5, surrounding its sides, andthe usual grate 6, adapted to support the iire.. Beneath the grate 6 isan ashpan 7, which may be ejected through a door 8, having a smalldamper 9 at the lower portion thereof, and the wall of the stove abovethe door 8 is provided with a second door l0, whereby fuel may beinserted endwise into the stove. The end of the stove is provided with adamper ll, adjacent the grate, and a small door l2 at the upper portionof the stove, whereby fuel may be inserted in the fire-box from abovewithout removing any of the lids I3 from the top.

Extending from the upper end of the partition 3 to the end of the stoveopposite to the fire-box, is a partition 14, substantially parallel tothe top of the stove and forming a ue or passage for the hot gases oriiames on their way to the chimney. A short distance below thispartition I4 is a second partition l5, substantially parallel theretoand forming with the partition 414 and the side walls of the stove, anair chamber or compartment I6 in which the air is heated to a very hightemperature before it is admitted to the oven. The side of the stove isprovided with a small damper 17, controlling the admission of air tothis chamber, and the partition 14 is provided with anupwardly-extending tube 18, through which the heated air passes on itsway to the even. Beneath the chamber 1G is a substantially verticalpartition I9 separating the space below into the reservoir 4 and awarming compartment 20, admission to which is gained by a door 2l in theside of the stove. A suitable faucet 23 may be provided for drawing hotwater from the reservoir 4. If desired, a second warming compartment 24may be provided, which extends beneath the reservoir 4 and warmingcompartment 20, and admission to this may be gained through a suitabledoor 25.

Located above the main stove body and adjacent the rear end thereof, isour improved oven having communication with the air heating chamber lGthrough the pipe I8, and also having a, Hue for the passage of the smokeand hot gases from the fire. This oven is substantially rectangular incross section, and is provided with a partition 26 sub-dividing the ovenproper from the iiue for the smoke, which flue communicates with thespace above the partition l4 by means of a suitable opening, asindicated in Fig. 4. The oven is provided with a partition 27,substantially parallel to the top of the oven and coni'iected with thepartition 26 at one end but free from the Wall of the oven at theopposite end. The partition 26 is provided with one or more perforations28 above the partition 27, and a second vertical partition 29 extendsparallel to the partition 26, and is provided with pertorations 30 and3l, adjacent its upper and lower extremities, respectively. A falsebottom 32 is provided within the oven substantially parallel to the topoi the stove body, and supported above the saine by downwardlyextendingilanges or side walls, as shown in Fig. 3. Any number ot shelves 33 maybe provided for supporting the material to be baked in the oven, andaccess to the oven is gained through a suitable door 34,

In the operation of our improved cooking stove, the flame and hot gasesfrom the [ire-box pass beneath the top of the stove and are directedagainst the partition 14 by a suitable deiiector, shown in Fig. 3. Uponreaching the back end oi the stove they pass through into the i'lue' inthe oven and thence to the chimney. The oven is heated by the passage ofthe hot gases beneath the bottom thereof and up through the flue. Freshair is admitted through the damper` l.7 and heated to a very hightemperature in the air-heating chamber i6, It then passes through thetube '18 to the oven where it strikes the false bottom and is deliveredinto the oven proper at the two ends. A portion oi this heated airpasses through the perforations 3] and is still further heated byContact with the flue, and is then delivered through the perfor-ations30 directly against the material being baked. All of the air, whetherentering the oven proper through the'perlorations 30 or whether passingaround the opposite end of the false bottom 32, can only escape bypassing around the end of the partition 27 and thence through theperfor-ations 28 to the flue. In escaping from the oven it carries withit, all ot the moisture which has been evaporated from the materialbeing cooked and all of the odors rising within the oven. Ii it is notdesired to circulate air through the oven during the cooking operation,the damper l7 may be closed and the cooking effected by the contact ofthe hot gases with the bottoni or under wall of the oven, in which casean automatic circulation otair within the oven would be effected throughthe perforations 30 and 3l.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:
